DOUBLE ACTING WATER- -WHEELI SPECIFICATION forming partpf Letters PatentNo. 313,621, dated March 1.0, 1885. Application filed January 21, 1884.(No model.)

To all whom it may concern:

Be it known that I, CHARLES WILLIAM RAU, of Allentown, in the county ofLehigh and State of Pennsylvania, have invented certa'in new and usefulImprovements in Double- Acting ater-Wheels, of which the following is afull, clear, and exact description.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a sectional side elevation of my improvement. Fig. 2 is asectional plan view of the same, taken through the line x m, Fig. 1.Fig. 3 is a sectional plan view of a part of the same, taken through theline y 3 Fig. I. Fig. 4 is an end elevation ofone of the inner blades ofthe wheel.

The object of this invention is to promote efficiency in the operationof water-wheels.

The invention consists in the construction and arrangement of parts, aswill be hereinafter fully described and claimed.

A represents a cylindrical case the upper end of which is flared or madefunnelshaped to receive the water. The upper end of the case A isattached to a suitable supportingframe, B, and its lower end is attachedto a spider or frame, 0, in which is formed a hearing, D, to receive thelower end of the vertical shaft E. The upper end of the shaft E-revolvesin hearings in a supporting-frame, F.

To the shaft 15, within the case A, are secured four (more or less)hubs, G, to each of which are attached four (more or less) paddles orblades, H. The blades H are in; clined, as shown in Fig. 1, and haveupwardly-projecting flanges it upon their inner ends, which are slottedto receive the fastening-screws, (see Fig. 4) so that the inclination ofthe said blades can be regulated, as may be desired. These flanges h arecurved, asshown in Fig. 2; but the arc of curvature is slightly greaterthan that of the hubs G, so that the said flanges will not bind whilebeing adjusted.

Upon the upper part of the shaft E is placed a tubular shaft, I, to thelower end of which, a little above the upper hub G, are attached theinner ends of four (more or less) blades, J, the outer ends of which areattached to upright bars K.

To the bars K, below each hub G, are attached the outer ends of four(more or less) blades, J, the inner ends of which project nearly to theshaft E. and which are inclined in the opposite direction from the saidblades H. The lower part of the tubular shaft I is centered upon theshaft E by a bearing, L,

formed upon or attached to the inner ends of 60 the bars M,whicl1 barsincline downward, and are attached at their outer ends to the upper endof the cylindrical part of the case A.

To the upper end of the tubular shaft I is attachetl a pulley, N, aroundwhich passes a belt, 0. The belt 0 also passes around a long pulley, P,attached to the countershaft Q.

To the shaft E, above the pulley N, is attached a pulley, R, aroundwhich passesa belt, S. The belt S is crossed and passes around thepulley P, as shown in dotted lines in Fig. 1. WVith this construction,when water is admitted into the case A it acts upon blades H J, andrevolves the shafts E I and pulleys R N in opposite directions, whichopposite motions, by means of the crossed belt-S and the straight belt0, act together to drive the pulley P with an increased power.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. The combination, with the shaft E, of a seriesofinclined blades, II, and. flanges h at the inner ends of said blades,said flanges being slotted, as shown, and pivotally secured to saidshaft, and a set-screw passing through the slot into the shaft,substantially as set forth.

2. The improved water-wheel herein shown and described,the sameconsisting, essentia ly, of the open cylinder A, having arms M 0 securedto the opposite ends thereof, hollow shaft I, provided with series ofimperforate inclined blades J, vertical bars K, to which the outer endsof said blades are connected, internal shaft E, and a series ofimperforate blades, H, secured thereto, said blades being arranged toproject between the blades J, sub stantially as described.
